To all whom it may comm:

Be it known that I, JAMES M. BALDWIN,

Brownville in the county of efierson a'nd ew York, have invented certain new and useful Improvements in Rossing- Machines and I do hereby declare the following to be a full, clear, and exact descriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawand to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in machines for ro'ssi bark and the object in view is to general y improve upon and render more eflicient this class of inventions and in so doing produce an apparatus which will reduce to minimum the 'manual labor required in handling the stock and greatly increase the capacity of the machine.

The invention consists essentially in the provision of an inclined stationary trough or tablehaving a conveyer passing longitudinally through a slot in the lowest portion thereof and upon which the blocks of wood fed means being provided for, automatically moving the block from the trough or table against the knives of a rotary cutter and, after the bark has been removed from the block, the latter is allowed to roll back by gravity upon the conveyer.

The invention compnses various details of construction, combinations and arrangeparts which will be hereinafter fully described and then specifically defined in the appendedclaims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a 'side elevation of the apparatus. Fig. 2 is an end view. Fig. 1s a top plan vlew. Fig. 4 is a sectional view throu h the, frictional clutch mechanism, and ig. 5 is an enlarged view in-elevation the frictional clutch mechanism.

Reference now being had to the details of the drawings by letter, A designates a casing for the rece tion of the disk cutter wheel B ing open to allow the block of wood to be rossed to come in contact with the rapidly rotating cutter knlves. Leading from the lower portion of said casing is a passageway D through which the bark, as it is rossed from the block, may be drawn away by any suitable suction force. A shaft E is jour naled in suitable bearin sin said casing and has a main driving pu ley E fixed thereto and to which power is applied for driving the plate carrying disk.

Mounted at any suitable locations are the hollow posts F having set screws F mounted in threaded openings therein and in each of said posts is mounted an adjustable standard G, the upper ends of which form bearings for the shafts H and H to which the sprocket wheels H and H are mounted, the former of said wheels being loosely mounted upon the shaft H while the latter is keyed to the shaft H.

K designates a trough or table having an elongated slot K in the bottom thereof in which slot the endless conveyer chain I travels,

which chain is mounted upon the sprocket wheels H and H Adjustably mounted upon the upright portions of said trough or table are the plates J connected at their outer ends to the'shafts H and H and each of said. plates has an elongated slot J through which the bolts J 2 carried by the side wall of the trough or table pass and suitable nuts are mounted upon said bolts for holding the plates in adjustable positions with reference to the trough or table.

By the provision of the adjusting means described, it will be noted that the trough or table may be held in difierent positions to adapt the apparatus for use in connection with various forms of rossing apparatus, as

it will be understood that my invention is of such a simple nature and so constructed that it may be readily adapted for use in connection with Various forms of debarkin "machines. Said trough or table has the inclined portions N which will cause the block, after the bark has been removed therefrom, to roll down upon the conveyer and be carried forward and deposited upon another conveyer and carried away to any suitable location without the necessity of the operator handling the block. A suitable endless conveyer, not shown, may be provided for carrying the blocks to be rossed to the conveyer which moves through the slot throwing yoke, designated by fetter engagement with the frictional clutch cone an of said trough or table, whereby the operator of the rossing machine may devote hlS entire attention to the machine without the icking u the and whi bh is in economy of necessity of losing time in billets or blocks to be rosse considerable of a desideratum time.

Splined to the shaft H is a frictional clutch cone L having a tapering circumference adapted to contact with the tapermg wall of a recess M formed in one face of the sprocket wheel H as shown clearl in the sectional view of the drawin s. clutch is pivotally connected at Q, to a projection Q upon the trough or table. The other end of said yoke is pivotally connected to a crank arm R fixed to the shaft R and to which shaft is connected a springpressed or weight-actuated foot lever 2 whereby the operator, by depressing said lever, may cause the friction cone to be thrown out of gear and cause the conveyer carrying the block to stop and, by releasing the foot lever, said conveyer will resume its forward movement.

Mounted in suitable bearings P upon said casing is a shaft P, having. a pulley fixed thereto and E designates a pulley which is fixed to the main driving shaft E and has belted connection E with the pulley P for driving the shaft P. A beveled pinion P is fixed to theshaft P and is in mesh with a similar beveled pinion P fixed to the shaft P mounted in bearings projecting from the casing of the rossing apparatus. Mounted upon the shaft P is a second pulley S, and S designates a pulley which is fixed to the shaft H and a belt S asses about the two pulleys S and S and a ords means for driving the shaft H.

Fixed to the shaft P is a sprocket wheel P, and T designates a yoke having arms T which are loosel mounted upon the shaft P one upon either side of the sprocket wheel P, and T designates a sprocket wheel having spindles T journaled in the outer end of said yoke T. A sprocket chain T passes about the two s rocket wheels P and T and is provided with spurs T upon the links of the chain T provided for the purpose of prickin into the block from which the bark is to be removed and causing the block to be fed up the inclined trough or table and against the knives of the rotary cutter. said yokeT affordingmeans for swinging the latter into such a position that the chain thereon will engage the block of wood and cause the same to be fed to the rotary cutter. Said yoke T is normally held at its farthest outer throw by a. lever D mounted upon a pivot D and having a link connection D D is adj usta-bly Q, is in.

A handle W is provided upon with the yoke while a counterpoise weight heldupon the long arm of said lever D I Mounted upon a vertically disposed pin X rising from the casing of the frameis a friction roller X against which the end of the block bears as the latter is' rotated by the endless chain T as the rotary knives are in contact with the bark of the block in rossing the same. In order to regulate the tensionof the conveyer chain T said yoke is provided with elongated slots T adapted to receive the adjusting bolts section of the yoke, suitable nuts being mounted upon said adjusting bolt. The operation of my rossing apparatus is as follows :The blade carrying disk is driven at a rapid s eed by power applied'to the main shaft. T 1e blocks to be rossed are fed forward on the conveyer I, which latter is constantly in motion excepting as the operator throws the friction clutch out of gear,

which will cause the conveyer I to come to a standstill. When the block upon the conveyer I comes to a location from which it is desired to cause the same to be carried in contact with the rotary cutter, the operator by depressing the foot lever may cause the conveyer to stop after which, by pushing the yoke T, toward the rotary cutter, the spurs upon the continuously 'movin endless chain T will contact with the block of wood and cause the same to be fedup the inclined wall of the trough or table and against the projecting knives of the rotary cutter. As the endless chain is constantly in motion, it will cause the block to rotate against the knives as they sever the bark from the block. It will be noted that the knives upon the r0- tary cutter are so positioned with relation to the block from which the'bark-is being removed that, when the knives contact with the bark, they will have passed by vertical positions and cause a downward draw out upon the bark which will have a tendency to hold the block in proper position, one end of the block bearin against the roller X. As soon as the bark is removed from the T carried by a block and as the operator releases his hold of the handle W, the counterbalanced lever D will cause the yoke T-to return to its farthest outer throw and the block from which the bark has been rossed, falling. by gravity upon the inclined wall of the trough, will roll down upon the endless conveyer I which is put in motion by the operator re- -moving his foot from the foot lever. When the block from which the bark has been removed reaches the end of the conveyer, it

may be automatically dropped upon any suitable conveyer mechanism from which it may be carried away from the apparatus.

From the foregoing, it will-be noted that, by the provision of an apparatus as shown and described, the operator is saved the work .1 of raising a block from the carrier and also handlin the block after the bark has been remove therefrom, as the block, when freed ofits bark, will fall by gravit u on the inclined wall of the trough and liach upon the carrier which may be put in motion by the o erator releasing his foot from the clutch v combination 'wlth a rotary cutter and casin ing' from the .casin t irowing lever.
